The US Navy PBY aircraft which had arrived at Wake Atoll on the previous day departed with passengers; these passengers would be the last US personnel to leave the atoll. During the day, 29 Japanese carrier aircraft from Soryu and Hiryu attack the island, followed by 33 land-based aircraft four hours later, damaging Battery D on Peale Island. Meanwhile, American intelligence indicated a large Japanese air force build-up in the Marshall Islands and a possible Japanese fleet present east of Wake Atoll, the latter of which seriously threatened the attempts to reinforce Wake.
